Short answer: a tie on sound quality. Both are rated 4.0/5 (#420 and #427 of 1291 in-ear headphones) at nearly the same price ($17.85 vs $16.99), so choose on features and fit.
What the CVJ Konoka does well: The median of 10 hobbyist measurements gives it a solid Harman preference score of 74 with a 2.17 dB spread. Watch for: A 5.3 dB peak near 2.0 kHz can make cymbals and sibilance sound sharp.
The case for the KZ EDA Balanced: A 7 single dynamic IEM that measures well (score 74 across seven measurements), with bass on target down to 20 Hz. The catch: The listing sells three tunings (Balanced, Bass and Hi-Res), so pick the silver Balanced version this rating covers.
Buy the CVJ Konoka or the KZ EDA Balanced on features: they are rated the same for sound quality at close to the same price.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
